The block foundation with embedded sleeve makes it possible to build a foundation less deeply or to dispense with the sleeve, which is complex in terms of formwork and reinforcement.

Due to special component designs, it may be necessary to adapt and manufacture the built-in parts accordingly. Small cross-sections are particularly important here.

Especially in the area of ​​machine foundations, there is often the requirement not to have a separating layer within the concrete block, which is why in the upper foundation areas there is often the requirement to carry out these with expanded metal so that no cracks occur.

Due to static requirements, it may be necessary to use perforated formwork sleeves.
In addition to the optimal bond (concrete slurry can penetrate through the material perforations and thus form an “interlock” with the foundation concrete, which also prevents the formwork sleeve from becoming detached before pouring), a higher shear strength capacity is also achieved.
